Specification of Letters Patent.

Application filed September 22, 1905. Serial No. 279,735-

To all whom it may concern.-

Be it known that I, ALBERT J. BARIEs, a citizen of the United States,and a resident of St. Louis, Missouri, have invented certain 5 new anduseful Improvements in Knife- Sharpeners, of which the following is aspecification containing a full, clear, and exact description, referencebeing had to the accompanying drawings, forming a part thereof.

ro My invention relates to a knife-sharpener;

I 5 plate is removable in order that it may be sharpened when the edgebecomes worn from use.

construct the frame of the knife-sharpener as that it may be adjusted soas to tightly hold the hardened-metal plate after the same has beennarrowed by being ground.

My invention consists in certain novel features of construction andarrangement of 2 5 parts, which will be hereinafter more clearly setforth, pointed out in my claims, and illustrated in the accompanyingdrawings, in which Figure 1 is a perspective view of my improvedknife-sharpener in position for use and a knife in position in thesharpener shown in dotted lines. Fig. 2 is a front elevation of theupper portion of the knife-sharpener. Fig. 3 is a vertical section takenon the line 3 Fig. 4 is a horizontal section taken on the line 4 4 ofFig. 1.

horizontal section taken on the line 5 5 of Tn the construction of myimproved knifesharpener the frame is made in two mating parts, eachcomprising a base-plate 1, from which extend upwardly the posts 2, andformed integral with thefront faces of the upper portions of said postsare the for- 4 5 wardly-projecting ribs 3, and the inner adj acent faces4 of these ribs are formed on lines diverging outwardly from a verticalline. The plates 1 are adapted to be'secured to a table or othersuitable base by means of screws 5, one of which passes through a slot6,

formed in one of the plates, thus providing "the means for adjustingthis plate and its post to and from the opposite plate and post. Formedin the lower portions of the inner ad- 3 5 j acent faces of the post 2are notches 7, and

formed integral with the rear sides of said A further object of myinvention is to so Flg. 5 1s a posts are the lugs 8. A screw 9 passesthrough an aperture formed in one of these lugs and into ascrew-threaded aperture in .the opposite lug, which screw is for thepurpose of drawing the two posts together.

10 indicates a hardened-metal plate, preferably of steel, the side edges11 of which are slightly beveled in such manner as that sharp edges areprovided on the front side of said plate. This plate is located betweenthe posts 2, its lower portion occupying the notches 7 and its upperportionextending upwardly between t e upper ends of said posts 2 betweenthe inclined faces 4 thereon. A retaining-plate 12 extends across thefront of the plate 10 just below the ribs 3 and is secured to said posts2 by means of the screws 13. The screw that enters the post carried bythe adjustable plate 1 passes through a slot 14, formed in the end ofthe plate 12, and thus provides for the adjustment of said plate 1 andits post.

My improved knife-sharpener is assembled by securing the fixed plate andpost to a table by means of one of the screws 5 and also securing theretaining-plate 12 to said post by means of one of the screws 13. Thesharpening-plate 10 is now arranged with one of its edges in the notch 7of the fixed post, after which the adjustable plate and post is broughtinto position next the opposite side of said plate 10. The screw 9 isnow inserted through the aperture in the lug 8 of the adjustable post,and as said screw is tightened the post is brought to bear against thelefthand edge of the plate 10. The remaining one of the screws 13 is nowinserted through the slot 14 and tightened, so as to lock the plate 12to the adjustable post, after which the remaining screw 5 is insertedthrough the slot 6 to secure the adjustable plate to the table.

A knife is sharpened with my improved device by inserting the bladebetween either edge of the plate 10 and the corresponding rib 3. Thensaid blade is moved so as to bear on the inclined face 4, and as saidknife is loosening the various screws of the adjustable plate and post,so as to bring new sharpening edges into use, or said plate can bereversed or turned upside down, so as to bring new sharpening edges intouse. When all of the sharpening edges of said plate have become dull,said plate can be removed and reground and again located between theposts and tightened thereinby manipulating the screws of the adjustableplate and post.

A knife-sharpener of my improved construction is simple, strong, anddurable, can be arranged for use on a table or on a wall, is easily andquickly adjusted to the width of the sharpening-plate, and said platecan be very easily reversed or adjusted between the posts and plates.

I claim 1. In a knife-sharpener, a pair of posts, means whereby theposts are adjustably clamped together, and a sharpening-plate heldbetween said posts; substantially as specified.

2. In a knife-sharpener, a pair of posts, a plate fixed to one of saidposts and adjustably secured to the opposite post, and a sharpening-plate clamped between said posts; substantially as specified.

3. In a knife-sharpener, a pair of posts in the inner faces of which areformed verticallydisposed notches, a plate fixed to one of the posts andadjustably secured to the opposite post, and a sharpening-plate arrangedbetween the posts and located in the notches therein; substantially asspecified.

4. In a knife-sharpener, a pair of posts, lugs integral with andprojecting outwardly from said posts, a draw-screw passing throug one ofsaid lugs and seated in the opposite lug, a plate fixed to one of theposts and adjustably secured to the opposite post, and asharpening-plate clamped between the posts; substantially as specified.

In testimony whereof I have signed my name to this specification inpresence of two subscribing witnesses.
